[Therapeutic efficacy of volume-guaranteed high frequency oscillation ventilation on respiratory failure in preterm infants with a gestational age of 28-34 weeks: a prospective randomized controlled study].

Objectives: To investigate the therapeutic efficacy of volume-guaranteed high frequency oscillation ventilation (HFOV-VG) versus conventional mechanical ventilation (CMV) in the treatment of preterm infants with respiratory failure.

Methods: A prospective study was conducted on 112 preterm infants with respiratory failure (a gestational age of 28-34 weeks) who were admitted to the Department of Neonatology, Jiangyin Hospital Affiliated to Medical School of Southeast University, from October 2018 to December 2022. The infants were randomly divided into an HFOV-VG group (44 infants) and a CMV group (68 infants) using the coin tossing method based on the mode of mechanical ventilation.

Thyroid dose assessments due to inhalation of I for nuclear medicine workers.

Background: In general, medical staff who work in nuclear medicine should be entirely safe in their professional environment. Nevertheless, we already know that the working environment of the nuclear medicine staff is not completely safe due to the handling of high amounts of radionuclides for diagnostic and therapy applications, which is especially relevant for I (as a non-sealed source).

Purpose: The goal of this study was to assess the inhaled I thyroid dose in nuclear medicine workers and to introduce a simple method for internal exposure monitoring.

Study of Low-Dose Radiation Workers Ionizing Radiation Sensitivity Index and Radiation Dose-Effect Relationship.

Background: In the present study, we analyzed radiation injuries to Chinese workers exposed to low-dose radiation. We discuss the relationships between dose and injury.

Methods: This study randomly selected 976 radiation workers who underwent occupational health monitoring.

Dose-effect relationships of C ions-induced dicentric plus ring chromosomes, micronucleus and nucleoplasmic bridges in human lymphocytes in vitro.

Purpose: The objective of this research was to explore the dose-effect relationships of dicentric plus ring (dic + r), micronucleus (MN) and nucleoplasmic bridges (NPB) induced by carbon ions in human lymphocytes.

Materials And Methods: Venous blood samples were collected from three healthy donors. C ions beam was used to irradiate the blood samples at the energy of 330 MeV and linear energy transfer (LET) of 50 keV/μm with a dose rate of 1 Gy/min in the spread-out Bragg peak.

Study of Indicators for Early and Rapid Diagnosis of Radiation Injury Is the Most Important in Patients With Cancer During Radiotherapy.

Objective: To establish a complete technical solution for the radiation biological dose estimation, to enable prediction of individuals' response to radiotherapy (RT), and to control treatment dose for reduced irradiation injury and promote repair; and to evaluate the risk of radiation-induced late effects for patients undergoing external photon beam RT and provide the reliable dose-response relationships.

Methods: Select 49 tumor patients using Co and linear accelerator for radiation therapy; initial radiation dose was 250 cGy. Chromosome aberration and blood count were analyzed before radiation therapy and 2 hours after the first day of RT.
